How To Integrate Web-based E-mail Accounts Into Mozilla Thunderbird

Many web mail hosting providers such as Gmail, Hotmail and Yahoo allow users to send and receive e-mails using e-mail client software (eg. Outlook Express, Thunderbird, Eudora) via standard POP3 and SMTP ports.

Gmail uses different ports for its POP3 and SMTP connections. Gmail requires users to connect to POP3 via port 995 and SMTP via port 587.

However, many companies firewall block traffic from accessing through non-standard ports. The standard ports for POP3 is port 110 and SMTP is port 25.

WebMail is an Mozilla Thunderbird extension that allows users to integrate web-based e-mail accounts such as Gmail, Yahoo, Hotmail, and many others into Thunderbird. It uses standard HTTP protocol to
connect and access your web mail account. Most companies enable HTTP traffic to pass through the firewall.
